Problem: Some Entourage Clients cannot sync "Inbox" with Exchange 2007 server via LAN. This occurred when a Admin accidentally hit uninstall on Rollup 3 for Exchange 2007. During the uninstall, he hit cancel then tried to restart services which didn't work then rebooted. The reboot caused havoc on the system, all Exchange and IIS services were disabled when server came back up. I switched the services to automatic and restarted them. Still OWA didn't come back, then fully uninstalled Rollup 3 for Exchagne 2007 and restarted server again. Everything seems to work except all Entourage users. After reinstalling a new UCC Certificate from Godaddy and Rollup 3 back into the box, I rebooted system. Next morning half the Entourage Clients work while the other half don't.
Situation: We have 50 MAC's on our LAN, varying between Entourage 2004 - 2008. Some Entourage 2004 work while others don't. All users on PC can Connect fine using Oultook. OWA works fine internally and externally for all users, including the affected. Affected MAC Users can get to all file shares and internet. The Exchange 2007 runs on Hyper V box in Guest Mode. I took a snapshot on 17th and this issue occured on 23rd. I have full backup on the emails server from 23rd and 24th.
Work Done: Thing we have tried
1. OWA address for account setting on the Entourage Clients with user address at end
2. Install Entourage 2008
3. Rebuilt IIS Virtual Directory
4. Installed Rollup 4 for Exchange 2007
5. Uninstalled all Rollups and reinstalled all Rollups
6. Moved the afftected users to a different Storage Group
7. Deleted and Rebuilt User Account (works fine until you import old mail back from PST)
8. Emtpy Inbox Cache
9. Recreated Identity in Entourage
10. Gave affected user admin rights and Static IP
This problem is very unique as all folders "Except Inbox" will sync. I was getting a certificate error on Entourage clients before the 23rd but that was because OWA cert did not match FQDN of server. I had not installed a UCC cert. I made the change to UCC cert on night of 23rd (after incident). The working Entourage users did not see the cert error anymore and OWA continued to work fine with new cert. I believe something happened during the afternoon of 23rd when this Admin had prematurely rebooted the server. The Event Logs don't tell of errors afterwards. Let know your thoughts, Thank You.
